Beveled clasp
Abstract
A clasp formed of beveled members, one a male member and the other a female
member, which interengage together and are retained in their connection
through capillary and frictional forces. The female member may contain a
slot, to facilitate its resilient widening, to receive the male member,
once inserted. The male member may include, at its frontal portion, a
slot, to provide for its compression, and formation of a bevel proximate
its front end to facilitate its interconnection with the female member
into the beveled clasp. A modification includes a beaded type connector
that interconnects together through the formation of a bead, interiorly of
the female member, and a complementary groove, formed proximate the
beveled front end of the male member, to facilitate the interconnection of
the clasp together, and to sustain its hold during coupling.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to a beveled clasp, formed of
complementary shaped male and female members, that interfit together, and
are secured in their retention through the generation of capillary and
frictional forces that hold the members together during clasping.
A large variety of clasps have been made available in the art, and such
clasps can be used for a variety of purposes, for application in
industrial settings for holding two parts together, but more particularly,
such clasps are frequently used in the jewelry art, for holding the ends
of necklaces, wrist bands, and other items together. Mainly, these prior
art style of clasps either use some form of detent means, for interlocking
the components together, to assure their retention, but separation of
these type of components frequently becomes difficult, particularly for
the physically impaired, such as the handicapped, who may be suffering
from an arthritic condition, multiple sclerosis, or other impediments that
significantly reduce the dexterity of the user to both apply, or remove,
the jewelry during usage.
Examples of the type of prior art as previously alluded to can be seen in
the prior art U.S. Pat. No. 5,155,893, to Nussberger, showing a coupling
device for use as a clasp or the like. As can be seen, the facility to
interengage the shown clasp utilizes the detent concept, where a shoulder
formed on one part of the coupling device will engage within a slot
provided upon the other part, in order to secure the shank and female
component together. This does require a little more effort, and secondly,
can be a little difficult in obtaining the separation of the clasp once
used.
An example of another prior art clasp is shown in the U.S. Pat. No.
4,364,155, to Synowicki, also upon a jewelry clasp, but in this particular
instance, the locking engagement is attained through notch alignment where
mechanism is provided to provide a latching of the clasp within the formed
notches of one part of the shown clasp. Thus, once again, the detent
principle is used to secure the clasp into its interengaging relationship.
The U.S. Pat. No. 4,242,778, to Kay, shows a press fit intelligent fastener
for random or lightly constrained assembly, but in this particular
instance, once again, it is the engagement within the annular cavity of
the formed spring biased pawl that secures these complementary components
together. Their separation, on the other hand, can entail a little more
dexterity, and one that is difficult for the handicapped to achieve.
The U.S. Pat. No. 4,184,232, to Marosy, shows another form of coupling, but
in this particular instance, the coupling is made through the bayonet lock
type of interconnection, which requires pivotal manipulation of the two
components for the coupling, to achieve their assembly, and also their
separation.
Another U.S. Pat. No. 3,540,091, to Marosy, shows a related style of
bayonet lock form of coupling device, for use for holding various items
together, such as the shown chain. It is to be noted, though, that all of
these prior art style of couplers require some form of spring biased force
exerting parts, to achieve their coupling, and which coupling forces must
be relieved, in order to achieve their separation.
The U.S. Pat. No. 3,234,615 to Martinez, shows a tensioning connector,
which again utilizes a variety of spring biased means for securing their
components together.
The U.S. Pat. No. 3,080,633, to Reddy, shows a separable fastener, which
again operates upon the spring biased feature, as can be seen for its leaf
spring components that engage within the slots formed behind the plunger
head of the shown fastener.
Another U.S. Pat. No. 3,286,316, to Marosy, shows a coupling means that
utilizes gearing or serrated surfaces to secure the attachment of the
shown coupling together.
The U.S. Pat. No. 3,367,000 to Schluter, shows a detachable fastening
device, again one which appears to function off of the bayonet lock style
of interconnection.
The U.S. Pat. No. 3,470,524, to Culver, shows a push-pull type of
connector, which contains a variety of interconnecting components,
including one that incorporates a rather comples cam style locking ring,
to secure the components of the connector together.
Another U.S. Pat. No. 3,487,512, to Marosy, shows a form of bayonet lock
style of interconnection for its disclosed coupling through the usage of a
cam like circular disc forming its locking element.
A further U.S. Pat. No. 3,540,087, to Marosy, shows a bullet shaped
coupling, likewise interconneced through a bayonet style of engagement, to
provide fastening of two components together.
A further U.S. Pat. No. 3,675,499, to Marosy, shows an earlier style of
coupling, through a spring biased member.
The U.S. Pat. No. 3,900,927, to D'Angelo, shows a separable fastener, where
a T-lock style of interconnection, which is normally spring biased into
engagement, can be assembled into a fastener.
The U.S. Pat. No. 4,055,057, to Kolman, discloses a coupling device for
opposed ends of a bracelet, utilizing a spring biased arcuate link for
securing one end of the bracelet to the other.
The U.S. Pat. No. 4,216,567, to Heinz, shows a flexible ornamental article
and fastener therefor, that appears to operate off the bayonet lock
arrangement.
A further U.S. Pat. No. 4,236,283, to Marosy, shows a bayonet style of
interconnecting coupling.
The U.S. Pat. No. 4,522,541, to Bidwell, shows a stud fastener receptacle.
The U.S. Pat. No. 4,679,959, to Cavallaro, shows a quick-connect/disconnct
connector, which appears to utilize a ball and socket type of
interconnection.
A much more complex locking device is shown in the axial style of locking
device set forth in the Barnes U.S. Pat. No. 4,709,454.
A further U.S. Pat. No. 5,095,594, to Marosy, shows a spring lock, again
off of the bayonet locking principle, for securing a coupling together.
The U.S. Pat. No. 5,347,696, to Otrusina, shows a quick-release connector.
The U.S. Pat. No. 3,080,633, to Reddy, shows a form of separable fastener,
which are linked together by means of spring bias leaf springs.
The essence of the current invention is to alleviate the effort that is
required to form a clasping connection between, for example, the ends of
jewelry, or other linkage, and which includes no moving component that
requires manipulation, or the exertion of any effort, to attain the
interconnection of the beveled clasp together, while its separation
requires nothing more than a slight brief twist, to achieve its
disconnection.
SUMMARY OF THE INVENTION
It is the principal object of this invention to provide a beveled clasp
that can be interconnected together, simply by the slight exertion of a
force interconnecting the male and female members together, and which
sustain their hold through capillary and frictional forces, while the
separation requires nothing more than a slight twist, to provide its
disconnection.
Still another object of this invention is to provide a much more simpler
way for interconnecting jewelry necklaces, dog tags, bracelets, and the
like together, through the exertion of only a slight force.
Still another object of this invention is to provide a beveled clasp that
can be interconnected together through a slide engagement.
Still another object of this invention is to provide a beveled clasp that
can be easily forced apart, just in the event should the jewelry,
necklace, or the like, be inadvertently caught in machinery, in order to
provide for its quick disconnection.
Still another object of this invention is to provide the interconnection of
a beveled clasp together, that is much more facilely applied by the
handicapped, such as those suffering from an arthritic condition, multiple
sclerosis, or other physical impairments, that make it very difficult for
the individual to manipulate their own Jewelry, either when applying it,
or disconnecting its clasp during removal.
Yet another object of this invention is to provide a beveled clasp that is
easily connected, very strong in retention, facile of removal, and can be
easily separated either manually, or simply pulled apart through the
exertion of a slight separating force.
Still another object is to provide a beveled clasp that is secured together
and held in securement by means of a capillary force.
Yet another object of this invention is to provide a beveled clasp that may
be secured together through a frictional engagement.
These and other objects may become more apparent to those skilled in the
art upon reviewing the summary of the invention provided herein, in light
of the description of the preferred embodiment.
This invention contemplates a beveled clasp, of the type that utilizes a
pair of beveled members, one comprising a female member, and the other a
male member, the two of which have a slight bevel along their length, and
which when forced together, through a slight exerting effort, can be
secured together by a combination of capillary action, and frictional
forces that strongly hold the clasp into its coupling relationship. The
female member may be formed having a cylindrical like portion at its
frontal end, and which includes one or more of a small slot extending
along its length, so as to provide some resiliency to retention of the
male member therein, when coupled. The male member may include also a
cylindrical portion, and have one or more slots provided therein, or the
male member may be formed as a solid member, having a longitudinal length,
and a portion of its length formed having a slot therealong, which when
compressed, forms a slight bevel to facilitate its insertion into the
female member, and retention therein, throught the sliding relationship
formed between the interior surface of the female member, and the beveled
external surface of the male member, for holding the same together. Once
again, that combination of capillary force, and frictional force, have a
tendency to hold these two members together, once the beveled clasp is
assembled, and tightly secure the ends of any jewelry, or the like, for
its securement about the wearer. Extensive testing has proven that the
clasp holds, and does not become free on its own, unless an exerting force
is made upon the item of jewelry, or a slight twist is exerted upon one or
the other of the male or female members, that readily provides for their
quick release when it is desired to seek their disengagement.
As is known, the frictional force that is generatd between two surfaces,
which exert a perpendicular force against each other, in their
relationship, provides a reactional frictional force that tends to hold
the components together, and the generated coefficient of friction that is
exerted between these two components, resists their movement or separation
relative to each other, which is what secures the beveled clasp of this
invention together, and sustains its hold, in addition to the capillary
surface force generated between the male and female components once they
are tightly interconnected.
This type of a clasp, formed utilizing these principles of physics to
sustain their connection is what makes the beveled clasp of this invention
distinct from the mechanical type of couplers as previously reviewed and
explained, and as shown, in the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENT
In referring to the drawings, FIGS. 1 through 3 disclose the beveled clasp
of this invention. The clasp 1 is shown interconnected, wherein the female
member 2 is receptive to the male member 3 and readily secures the two
together, during their interconnection. As noted, the female member 2 is
formed as a sleeve or cylindrical portion 4 which has at least, but
preferably two, diametrically opposed slots 5 formed partially along their
length, and which allows for the female member to be slightly spread, to
furnish an internal contact which is complementary to the male member,
while held together by surface adhesion between the two beveled members
when coupled. The female member, and more specifically along its
cylindrical or sleeve like portion 4, includes an interior surface 6,
which due to the widening of the slots 5, during coupling, forms a mating
surface engagement with the slightly beveled surface 7 of the male member
3, during interconnection. The male member 3 may also comprise or be
formed of a cylindrical portion 8, and which may include one, but
preferably a pair of diametrically opposed slots, as at 9, partially along
its length, and wherein the outer exterior surface 10 proximate the slot 9
may be compressed, to form a slightly tapered surface, as at 11, which not
only facilitates the insertion of the male member within the female
member, but provides concentricity between their surfaces, to form that
flush engagement that provides for the formation of the capillary forces
that hold the two members together, once clasped, in addition to the
frictional force that prevents their disengagement, once interconnected.
It can also be seen that various forms of linkages, such as the rings 12
and 13 may be rigidly connected to the back ends of the members, in order
to provide means for interconnecting with the ends of any jewelry, such as
noted at J.
FIGS. 4 and 5 provide a top view of the beveled clasp, and its female
member 2, and the male member 3, that readily shows the beveled
relationship 11 proximate the forward end of the member 3. The back ends
of the slots 5 formed of the female member 2 can be seen at 14 and 15.
FIG. 6 provides an end view of the female component when it is slotted, and
compressed, to provide a resilient type of means that can be expanded,
upon insertion of the female member therein, and provide for that
frictional and capillary engagement between the components and which
resist their separation, unless required. Likewise, FIG. 7 discloses an
end view of the male component, with its diametrically opposed slots, as
at 9, and which member when compressed, forms the slight bevel, as shown
in FIG. 5.
FIGS. 8 through 11 disclose a beveled clasp, of the type as referred
herein, and which includes the further feature of a beaded and grooved
connection that interengage and lock these components together, and secure
them, unless a tensioning force is exerted upon the two components,
pulling them apart, after overcoming their resistance to separation. As
can be seen, the female member 16 is formed as a cylindrical portion,
having an opening 17 provided through its interior, and extending
substantially its length. Towards the frontal portion of the member is
provided an indentation, which forms a bead 18 around the inner
circumference of the member. An eyelet 19 is fastened, as by solder, or
the like, at the back end, to provide for its interconnection with other
components, such as the end of a necklace, bracelet, or the like. Its
frontal end is opened, as at 20, and into which the male member 21 may
insert. The male member also has longitudinal length, having a base 22, to
which an eyelet 23 is secured, while the front of the male member 21 is
contoured at a bevel, as at 24, and includes a slot 25, and an integral
groove 26 proximate the frontal portion of the member 21. Thus, when the
front of the member 21, and more specifically its beveled portion 24 is
inserted within the female member, the slot allows a slight compressing,
to provide clearance for the circumferential extremity 27 of the beveled
portion to clear the bead 18, at which time further insertion of the
member 21 seats the bead 18 within the groove 26, to provide a securement
of these members together. A slight pulling upon the two members, as at
their eyelets 19 and 23, can force their disconnection, allowing for
removal of the item of jewelry, or other components to disconnection.
Variations or modifications to the subject matter of this invention may
occur to those skilled in the art upon reviewing the invention as
described herein. Such variations or modifications, if within the spirit
of this invention, are intended to be encompassed within the scope of any
claims to patent protection issuing upon this invention. The description
of the preferred embodiment set forth herein is done so for illustrative
purposes only.
